Be it known, that I, EDWARD CUNNIFF, a, ClallnS "-III 1-,, i: :m-E' '1 5citizen of the United States, and a resident of New Bedford, count)" ofBristol State of 5 Massachusetts, have invented on improvement in'lhrenddarting Meohanism for Looms, of which the following description,in ,eonnection with the accompanying drawings is a. specification,lilioeliaiacivrs on the m dIlLWlllgi-l representing l ke parts.

' This uiveiition relates more especiullyto automatic iii[mg-replenshing loo-ms of the so-ealled fl'e'ele1""t \j)e, herein the runningfilling is replenished prior to eoniplme ere 'do'gibl i' ork looms. j IStates patent to DHLPKH, No. 683,423,;dated September 24; 1901,muchalriist'n' is'fpi'ovided to piirt the thread of the 'Ifaniftigcateh"or'elamp the severed thrvml and I carry lfiorwarduso that it will bebrought intqlhomn e of temple thread-cutter [u be hon] tho loom him afilling-fork utthe adjacent the replenishing movie-mien; fork. islocated between the temple 'd-cirtter m d the sepn rme purl mg ml'being"'i1i practice"mounted on =i lml1lo- ,feeler. the latter returnsto normal inoperative osition, withtho Pill'llfli lliroml held by t ieeliunji, MIC/ll thread is drawn across or against the filling-fork, andsumvtimes this causes the lhread to be drown out realrwardly from theclamp before it can be i severed by the iemple thread-cutter. Whenoccurs the pier-o of thread is apt to lml 4d eairriedbac inlo the clothand market: am imi reflection then-in.

ho novel features of my invention will be fully described in thosubjoined specification '1 Figure 1 is a top 111,11 View of asuflicientxo portion of a, rloubleork automatic. fillihgerlaw';pleni'sliing loom having ii temple thread-cu1a- Z mr and clamping andparting imegns withmy invention applied thereto. :Fig. 2 is aside J50elevation of the clamping and parti means in normal orretracted;position withil the vlmnp closed.

The upper end of the feeler Y is notched at 9o 1, Figs. 2 and 3. .nreceive the filling-thread when the feeler is moved into opera tiyetposklion :uljml-ut. the mouth of the shuttle-lion l Fig. l, and a fixedcutting-blade 2 is serum-(l to the llL'lCl at the loweiweglge orl'ace i1 ol KIM-notch 1; such fare having a: transverse shoulder 3 thereon. IThe movable member 4 is mounted on the 1 screw-stud 4 Fi 3, amlruktsirzninsl. the

llat'side of the feel r, this member serving as ice i a. combinedclumping-jaw and'cuttmgJr'lnde.

its lower edgecooporating with the blade 2 to part the filhng-thread,andit also cooperates with the relatively fixed mei'nber 7'. (if-{thethreud-elamp, said member Thriving a ininsverse shoulder 5 in ulineioentwith the shoul- T and the feeler der 3. This fixed member 7 is held inplace by the stud 4 and by a pin 10 in the feeler,

assed through a slot 9 in the member 4, the atter having a dependin heel9, a springwasher 11 being interposed between the head of the stud 4 andthe member 7 of the thread-clamp, pressing the latter against theblade-jaw 4, and the latter is in turn held against the side of thefceler. I have thus made the thread-clamp and the threadparter eachcomprise a movable and a relatively fixed member, and the two deviceshave the movable member 4 in common, as in Patent No. 683,423, referredto.

When the parter and clam are in operative osition, the filling-threadwill enter the notch 1 of the feeler and the alined shoulders 3 and 5will pass behind the thread, serving to guard against the thread drawingback out of the notch before the clamping and parting action. Thereuponthe member 4 is operated by engagement of the lay with the heel 6, as isusual, and the thread t, Fig. 4, is

tossed down over the member 7 between it and the blade-jaw 4 and as thelatter member'reaches dottedine position, Fig. 4, it will cooperate withthe fixed cutting-blade 2 and part the thread.

Referring to Fig. 1, I ing-forks g at opposite sides of the loom, thefork g" being located between the temple Y, and as the feeler returns tonormal position the clamped filling end i is drawn forward a ainst thefork g". his tends to cause the lling to slip or draw out of the clamprearwardly, so that it cannot be brought into range of the templethread-entter a; but herein the shoulder 5 acts to resist such rearwardpull on the thread, aiding the clamp in retaimng its hold on the threadun til it 18 positioned roperly for the cutter c. As the thread haseenparted, the shoulder 3 at this particular time has no function; butwhen the thread first enters the notch 1 of the feeler both shouldersact to prevent any twist or kink in the thread, withdrawing it from thenotch before it is clamped and parted.

Herein I have dispensed with the threadcatcher of the patent referredto; but the arm E, having a head e, is provided with a have shown twolillcam device e, Fig. 2, substantially as in said atent, to cooperatewith a pin 12 on the blade-jaw 4 and open the latter as the feeler movesforward.

When the clamp and parter are moved bodily into operative position, theblade-jaw 4 is open and the heel 6 IS in the path of a portion of thelay to be struck as the same comletes its forward beat, acting throughthe lads-jaw 4 to clamp and part the thread t ad'aeent the shuttle.

he action on the return of the feeler to normal position has beenalready described.

Having fully described my invention, what I claim as new, and desire tosecure by Lettors Patent, is-

1. in an automatic filling-replenishing loom, a thread-parter and athread-clamp, to act upon the thread. of the filling-supply to lll'abandoned, said partcr and clamp having a movable member in common,means on the relatively fixed member of the clamp to retain the threadin position and )revent it from drawing out of the clamp .alter it hasbeen parted, and means operating through said movable member to eil'ectclamping and parting oi the thread upon replenishment of lilling.

2. in an automatic filling-replenishing loom, a thread )arter and athread-elamp, to not upon the thread of the filling-supply to beabandoned, said porter and clamp having a movable member in common, atransverse shoulder on the relatively fixed member of the clamp to passbehind the thread and retain it in position to be acted upon, and toprevent it thereafter from drawing out of the clamp, and means operatingthrough said movable member to effect clamping and parting of the threadupon replenishment of filling.

3. In an automatic filling-replenishing loom, a thread-porter and athreadmlamp, bodily movable upon replenishment of filling into positionto act upon the thread of the filling-supply to be abandoned, the parterand clamp including a common movable mmnber, a transverse shoulder onthe relalively fixed member of the clamp to pass behind the thread andretain it in position to he acted own, and means acting throu h saidmovable member to clamp and part t 0 thread, the shoulder alsocooperating with the clamp to hold the thread after it has been parted.

4. In a loom provided with automatic lilling-replenishing mechanism, ashuttleieeler having a tl'iread-receiving notch in its end, a transverseshoulder on the lower face ol'thc notch, a fixed parting-blade adjacentthe notch, a elamping iaw mounted on the wieeler, adjacent and parallelto the blade and having a transverse shoulder alined with the "shoulderon the feeler, a combined parting blade and clamping-jaw movably mountedon the [color between the fixed blade and aw, the shuttle-feeler beingadapted to move into operative )osition prior to change of filling, tothere )y position the parting and clamping devices to act upon thethread of the filling-supply to be abandoned, the alined shoulders atsuch time passing behind the thread and retaining it in the clamp afterit has been parted, and means to act upon the movable combined blade andjaw to effect clamping and parting of the thread.

5. In an automatic filling-replenishing loom, two filling-forks, locatedat opposite sides of the loom, a temple thread-eutter at thereplenishing side of the loom, e threadpert-er anda, thread-clam at thesame side, to e'ct'u'pon the thread 0 the filling-Sn ply to beebandonedfiseid perter and clamp having a movable member in common, atrans- =.ve1se shoulder on the relatively fixed memlier of;the clamptopess hehind the thread, 1
